Abstract

Abstract:

Rainstorm disaster is a common kind of disaster that threatens the safety of urban life and property, and the historical relics exposed therein are faced with the great inundation risk. Scientifically predicting the inundation risk of historical relics and carrying out rescue work in time can effectively improve the rescue efficiency. Taking 154 historical relics in Henan province as the research object, based on SCS-CN model and GIS spatial analysis technology, 65 catchment areas containing historical relics were extracted through hydrological analysis to study the risk of historical relic inundation under rainstorm scenarios. Firstly, the critical rainfall of historical relics submerged was calculated in each catchment area. Then, comparing with the actual rainfall scenarios during the “July 20 Henan Rainstorm” period, from 8:00 on July 20 to 6:00 on July 21, from July 20 0:00 to 21 24:00, and from July 18 0:00 to 21 24:00, the areas with inundation risk were identified respectively. Finally, the inundation risk of historical relics was systematically evaluated. The results show that: (1) Extreme rainfalls for many consecutive days can easily create widespread ponding in the catchment area, and as the duration of continuous rainfall increases, the threat of inundation of historic relics becomes more severe; (2) The catchment areas with low critical rainfall are more likely to be flooded when rainstorm comes, and the inundation risks of historical relics in these areas are relatively high; (3) Topographic conditions and development degree have become important factors affecting the inundation risk of historical relics under extreme rainfall scenarios, so that areas with high risk are mostly located in low-lying areas with high development degree; (4) The planning should focus on high-risk points and their corresponding catchment areas by implementing classified prevention and control, building a flood control and disaster relief system, and establishing a risk early warning mechanism to effectively improve the urban resilience. The research results are expected to provide useful reference for the emergency management of historical relics under the rainstorm disaster scenarios.
